Cowboy Bebop said:Mine had about the same range when I installed it... then I saw a tin foil mod that more than trippled it's range!
easy fix, unfortunately the page that hosted the DIY is no longer there.

All you need is some aluminium foil although copper tape is better since it is thicker. If you can find thicker aluminum foil, it will help. Otherwise, a piece of posterboard (cereal box?) wrapped in foil will do the trick, too.
AndyM said:I also added wire to the antennae on the opener and it added a good amount to the range I have.
AndyM said:Take a piece of wire (like 2-3')
Cowboy Bebop said:aluminum foil cut into a strip about 9" long x 1.5" wide then folded the foil in half to .75" then in half again till you had a piece 9"x3/8" and this was then attached to the internal antenna of the UGDO. you wind about 2 inches of the foil arounf the antanna bar, then run the rest out the side of the case
Terry Kennedy said:To the original poster - your BMW Center will probably agree to test to see if you can stand on your head if you offer them $150. For an hour of labor they'll probably futz with it and say they can't find anything wrong (with the Homelink, not your headstand ).
shaftdrive said:How does the BMW technician TEST range on the homelink system?
I could throw a watermelon farther than my homelink signal seems to travel.
Even with the garage door dead ahead, my homelink range is about 20 feet.
Face off at the slightest angle, & range drops to near zero.
I scheduled a BMW Service Appointment, which, the Service Advisor says will cost only $150. Cheap. But wait. I ask what test they perform. He can't find any. I ask if they have an antenna and a receiver with a power meter. Nope. Do they even have range & offset specifications. Nope. So what will they do for this inexpensive test? He says they'll call BMW and ask how to test the homelink system.
Does any of this make sense to you?
Searching Bimmerfest, I find lots of articles ... but not the answer to this question (In keeping with my signature, I'll post these references separately so we collect the knowledge so others also benefit from all my questions).
My question for BMW enthusiasts is:
What does the BMW dealership typically do to test range on a homelink system (other than "Call Home").
